My AH has smoked and drank most of his life. He has had 3 heart attacks, triple bypass heart surgery, lung surgery, back surgery and has COPD. He also only has one functioning kidney. He is 60 now, but had his first heart attacks in his 40's, his bypass at 49. His lifestyle caught up with him, yet he continues to drink. He did give up smoking after his lung surgery, but chews tobacco, so did not give up his nicotine addition.
